Risk of Bleeding Versus Venous Thromboembolism After Surgery for Breast Cancer: A National Surgical Quality Improvement Program Analysis.

INTRODUCTION: Patients who undergo surgery for breast cancer are at risk for venous thromboembolism (VTE) and bleeding, which can lead to significant consequences on outcomes. This study examined factors related to VTE and bleeding risk in breast cancer surgery, with and without reconstruction. We also investigated the relationship between operative time and resident involvement on bleeding and VTE risk. METHODS: Using the ACS-NSQIP database, patients who underwent mastectomy, implant, pedicled, or free flap reconstruction from 2005 to 2021 were identified. Resident involvement was available from 2007 to 2010. We fitted two logistic regressions to model the log odds of bleeding occurrence and VTE as linear functions of procedure type, controlling for age, body mass index, and comorbidities. RESULTS: Implant reconstruction had significantly reduced 30-d incidence of bleeding, compared to those who underwent transverse rectus abdominus muscle flap (P < 0.001). Free flap was associated with a significant increase in bleeding but not VTE risk (P < 0.001; P = 0.132). Increase in operative time significantly increased the risk of bleeding and VTE (P < 0.001). For surgeries with resident involvement coded, there was no significantly increased risk of bleeding or VTE (P = 0.600; P = 0.766). CONCLUSIONS: Implant reconstruction remains the procedure with the lowest risk of both bleeding and VTE. Free flap reconstruction did not show a significantly increased risk of VTE, potentially expanding reconstruction options for patients previously excluded from autologous reconstruction. Surgeons should be mindful of operative time, with re-evaluation of risk factors with each additional hour of surgery, irrespective of reconstruction type. Resident involvement in surgeries should continue to be encouraged by faculty.

Four-level ACDF surgical series 2000-2022: a systematic review of clinical and radiological outcomes and complications.

OBJECTIVE: The primary objective of this investigation is to systematically scrutinize extant surgical studies delineating Four-Level Anterior Cervical Discectomy and Fusion (4L ACDF), with a specific emphasis on elucidating reported surgical indications, clinical and radiological outcomes, fusion rates, lordosis correction, and the spectrum of complication rates. METHODS: The literature review was conducted in adherence to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, employing the MEDLINE (PubMed), Embase, and Scopus databases. This analysis encompasses studies implementing the 4L ACDF procedure, with detailed extraction of pertinent data pertaining to surgical methodologies, types of employed interbody cages, clinical and radiological endpoints, rates of fusion, and the incidence of complications. RESULTS: Among the 15 studies satisfying inclusion criteria, a marginal increment in the year 2022 (21.4%) was discerned, with a preponderance of study representation emanating from China (35.7%) and the United States (28.6%). 50% of the studies were single-surgeon studies. Concerning follow-up, studies exhibited variability, with 42.9% concentrating on periods of five years or less, and an equivalent proportion extending beyond this timeframe. Across the amalgamated cohort of 2457 patients, males constituted 51.6%, manifesting a mean age range of 52.2-61.3 years. Indications for surgery included radiculopathy (26.9%) and myelopathy (46.9%), with a predilection for involvement at C3-7 (24.9%). Meta-analysis yielded an overall complication rate of 16.258% (CI 95%: 14.823%-17.772%). Dysphagia (4.563%), haematoma (1.525%), hoarseness (0.205%), C5 palsy (0.176%) were the most prevalent complications of 4L ACDF. Fusion rates ranging from 41.3% to 94% were documented. CONCLUSION: The 4L ACDF is commonly performed to address mylopathy and radiculopathy. While the surgery carries a complication rate of around 16%, its effectiveness in achieving bone fusion can vary considerably.

The Financial Impacts of the COVID-19 Crisis on the Practices of Cosmetic/Aesthetic Plastic Surgeons.

The global pandemic of coronavirus 2019, or COVID-19, has undeniably impacted all facets of healthcare, affecting both its function and provision. Due to the cessation of all non-emergent surgical cases in the USA and worldwide, the professional lives and practices of many physicians have been negatively affected. However, among different physicians and specifically plastic surgeons, cosmetic/aesthetic plastic surgeons have been disproportionately affected by the COVID-19 pandemic as the majority of their cases are semi-elective and elective. The ability to perform semi-elective and elective cases is dependent on state and local authorities' regulations, and it is currently uncertain when the ban, if ever, will be completely lifted. Financial constraints on patients and their future inability to pay for these procedures due to the COVID-19-related economic recession are things to consider. Overall, the goal of this unprecedented time for cosmetic/aesthetic plastic surgeons is for their medical practices to survive, to conserve cash flow although income is low to none, and to maintain their personal finances. In this paper, the authors review the financial impacts of the current COVID-19 pandemic on the practices of cosmetic plastic surgeons in the USA and worldwide, along with some potential approaches to maintain their practices and financial livelihoods.

Furthermore, they describe the contribution of their research group to the field of adult CM-I treatment, including association of increased body mass index with severity of CM-I and syringomyelia, relevant surgical anatomy, and surgical technique of 270° microsurgical decompression of foramen magnum. The authors also report on common complications in the literature and describe techniques for prevention of complications.

Spontaneous Bleeding in Vestibular Schwannoma in Patients on Oral Anticoagulant Therapy: Report of Two Cases and Review of Literature.

OBJECTIVE: Anticoagulant therapy is a risk factor for repeated intratumoral hemorrhage and acute enlargement of a vestibular schwannoma (VS) with neurological deficits. Therefore, we describe two cases of patients on oral anticoagulant therapy with intratumoral hemorrhage in which anticoagulant therapy prior to surgical resection was discontinued. We also discuss other similar cases from the literature since this is a rare event. CASE REPORTS: We described the two cases of intratumoral hemorrhage in acoustic neurinoma and conducted a literature review of similar cases of patients with intratumoral hemorrhage in acoustic neurinoma who were also on oral anticoagulants. Both patients presented with CN-VII palsy prior to surgery; both also fully re-covered after surgery except for hearing loss on the tumor side. Our literature review found 50 cases of VS (reported as vestibular schwannomas in the literature) with intratumoral hemorrhage. From this total, 11 patients used oral anticoagulant therapy with reported poor outcomes and high mortality; 9 of these 11 cases were reported in the past 20 years. The incidence is expected to rise due to increased use of anticoagulant therapy due to onset of atrial fibrillation, atherosclerosis, and thromboembolism from longer human lifespan. CONCLUSION: Anticoagulant therapy represents a risk factor for intratumoral hemorrhage and acute enlargement of VS tumor mass with neurological deficits.

Safety of robotic surgical management of non-elective colectomies for diverticulitis compared to laparoscopic surgery.

Non-elective minimally invasive surgery (MIS) remains controversial, with minimal focus on robotics. This study aims to evaluate the short-term outcomes for non-elective robotic colectomies for diverticulitis. All colectomies for diverticulitis in ACS-NSQIP between 2012 and 2019 were identified by CPT and diagnosis codes. Open and elective cases were excluded. Patients with disseminated cancer, ascites, and ventilator-dependence were excluded. Procedures were grouped by approach (laparoscopic and robotic). Demographics, operative variables, and postoperative outcomes were compared between groups. Covariates with p < .1 were entered into multivariable logistic regression models for 30 day mortality, postoperative septic shock and reoperation. 6880 colectomies were evaluated (Laparoscopic = 6583, Robotic = 297). The laparoscopic group included more preoperative sepsis (31.6% vs. 10.8%), emergency cases (32.3% vs. 6.7%), and grade 3/4 wound classifications (53.3% vs. 42.8%). There was no difference in mortality, anastomotic leak, SSI, reoperation, readmission, or length of stay. The laparoscopic group had more postoperative sepsis (p = 0.001) and the robotic group showed increased bleeding (p = 0.011). In a multivariate regression model, increased age (OR = 1.083, p < 0.001), COPD (OR = 2.667, p = 0.007), dependent functional status (OR = 2.657, p = 0.021), dialysis (OR = 4.074, p = 0.016), preoperative transfusions (OR = 3.182, p = 0.019), emergency status (OR = 2.241, p = 0.010), higher ASA classification (OR = 3.170, p = 0.035), abnormal WBC (OR = 1.883, p = 0.046) were independent predictors for mortality. When controlling for confounders, robotic approach was not statistically significantly associated with septic shock or reoperation. When controlling for confounders, robotic approach was not a predictor for mortality, reoperation or septic shock. Robotic surgery is a feasible option for the acute management of diverticulitis.

Microsurgical resection of giant T11/T12 conus cauda equina schwannoma.

In this video, we highlight the anatomy involved with microsurgical resection of a giant T11/T12 conus cauda equina schwannoma. Spinal schwannoma remains the third most common intradural spinal tumor. Tumors undergoing gross total resection usually do not recur. To our knowledge, this is the first video case report of giant cauda equina schwannoma resection. A 55-year-old female presented with paraparesis and urinary retention. Lumbar spine MRI revealed a contrast-enhancing intradural extramedullary tumor at the T11/T12 level. Surgery was performed in the prone position with intraoperative neurophysiology monitoring (somatosensory and motor evoked potentials-SSEPs and MEPs). T11/T12 laminectomies were performed. After opening the dura and arachnoid, the tumor was found covered with cauda equina nerve roots. We delineated the inferior pole of the tumor, followed by opening of the capsule and debulking the tumor. Subsequently, the cranial pole was dissected from the corresponding cauda equina nerve roots. Finally, the tumor nerve origin was identified and divided after nerve stimulation confirmed the tumor arose from a sensory nerve root. The tumor was removed; histological analysis revealed a schwannoma (WHO Grade I). Postoperative MRI revealed complete resection. The patient fully recovered her neurological function. This case highlights the importance of careful microsurgical technique and gross total resection of the tumor in the view of favorable postoperative neurological recovery of the patient. Intraoperative use of ultrasound is helpful to delineate preoperatively tumor extension and confirm postoperative tumor resection.

Impact of the COVID-19 Pandemic on the Education of Plastic Surgery Trainees in the United States.

The current COVID-19 pandemic has vastly impacted the health care system in the United States, and it is continuing to dictate its unprecedented influence on the education systems, especially the residency and fellowship training programs. The impact of COVID-19 on these training programs has not been uniform across the board, with plastic surgery residency and fellowship programs among the hardest hit specialties. Implementation of social distancing regulations has affected departmental educational activities, including preoperative, morbidity and mortality conferences and journal clubs; operating room educational activities; as well as the overall education of plastic surgery trainees in the United States. Almost all elective and semielective surgeries across the United States were suspended for a few months during the COVID-19 pandemic; this constitutes a significant portion of plastic surgery cases. Considering the current staged reopening policies, it may be a long time, if ever, before restrictions are completely lifted. In this paper, we review the multidimensional impact of the current COVID-19 pandemic on the training programs of plastic surgery residents and fellows in the United States and worldwide, along with some potential solutions on how to address existing challenges.

Combined Microsurgical, Endoscopic and Neuronavigation Assisted Transseptal- Transsphenoidal Resection of Pituitary Tumors.

OBJECTIVE: To describe the technical nuances of multimodal transseptal-transsphenoid surgery for pituitary tumors using a combination of microneurosurgery, neuroendoscopy, and electromagnetic neuronavigation. MATERIALS AND METHODS: A transnasal approach to the sella is performed endoscopically and widely exposed by an otolaryngologic surgeon. Surgery is next performed by the neurosurgeon with microscope and neuronavigation for microsurgical resection of pituitary tumors. Neuroendoscope is also used at the end of surgery to confirm tumor resection and inspect operative site. During surgery, the patient's head, angle and height of the microscope, and position of the table are repositionable to allow for multiple angle views. Abdominal fat harvested prior to the procedure is used to ensure cerebrospinal fluid seal. RESULTS: The senior author (KIA) has used the combined approach with 84 consecutive patients. Radical resection was achieved in 66 patients, subtotal in 11, and partial in 7. There were no perioperative complications. Six patients experienced postoperative transient diabetes insipidus. The pituitary gland and stalk were preserved in all cases. Visual symptoms were improved in 78% and endocrinological symptoms in 56% of cases. CONCLUSION: This combined approach is safe and effective. It increases the efficacy and radicality of surgical resection, helps to preserve the pituitary gland, and improves and resolves preoperatively altered patient hormonal function and impaired vision. It also reduces complications, provides less postoperative pain and discomfort, reduces the surgery time, and enables a shorter hospital-stay.
